Abstract

La présente invention concerne un procédé de commande du niveau de puissance d'émission. Ce procédé consiste à recevoir une commande du niveau de puissance d'émission et un signal de référence au niveau d'une station d'émission, la commande du niveau de puissance d'émission indiquant une augmentation ou une diminution du niveau de puissance d'émission pour la station d'émission ; à mesurer un niveau de puissance reçu pour le signal de référence et à comparer ce niveau mesuré à un niveau de puissance d'émission du signal de référence pour produire une estimation de l'affaiblissement de propagation du signal de référence ; à déterminer la valeur de l'ajustement du niveau de puissance d'émission nécessaire, sur la base de l'estimation de l'affaiblissement de propagation ; à ajuster un niveau de puissance d'émission de la station d'émission en réponse à la commande de puissance d'émission, sur la base de la valeur d'ajustement déterminée ; et à émettre un signal de communication dont le niveau de puissance d'émission a été ajusté.
